Insulin and diabetes pills are the two kinds of medicines used to lower blood glucose.

If You Use Insulin

You need insulin if your body has stopped making insulin or if it doesn't make enough. Everyone with type 1 diabetes needs insulin, and many people with type 2 diabetes do too.

Insulin can't be taken as a pill. You'll give yourself shots every day or use an insulin pump. Insulin pumps are small machines that connect to narrow tubing, ending with a needle just under the skin near the abdomen. Insulin is delivered through the needle.

Keep extra insulin in your refrigerator in case you break the bottle you're using. Don't keep insulin in the freezer or in hot places like the glove compartment of your car. Also, keep it away from bright light. Too much heat, cold, and bright light can damage insulin.

If you use a whole bottle of insulin within 30 days, you can keep that bottle at room temperature. If you don't use a whole bottle of insulin within 30 days, then store it in the refrigerator.

If You Take Diabetes Pills

If your body makes insulin, but the insulin doesn't lower your blood glucose, you may need diabetes pills. Some pills are taken once a day, and others are taken more often. Ask your health care team when you should take your pills.

Be sure to tell your doctor if your pills make you feel sick or if you have any other problems. Remember, diabetes pills don't lower blood glucose all by themselves. You'll still want to follow a meal plan and exercise to help lower your blood glucose.

Sometimes, people who take diabetes pills may need insulin shots for a while. If you get sick or have surgery, the diabetes pills may no longer work to lower your blood glucose.

You may be able to stop taking diabetes pills if you lose weight. (Always check with your doctor before you stop taking your diabetes pills.) Losing 10 or 15 pounds can sometimes help you reach your target blood glucose level.

If You Don't Use Insulin or Take Diabetes Pills

Many people with type 2 diabetes don't need insulin or diabetes pills. They can take care of their diabetes by using a meal plan and exercising regularly.
